You can compost it, bag it and sell it (makes GREAT fertilizer if you keep urine soaked shavings to a minimum), get a dumpster and have the trash folks deal with it, spread it in a large pasture or area, or burn it.
Since you have some room, spread it away from the barn and other structures, wait until it dries, then push it all toward the middle and light the sucker up! Not exactly great for the environment, but it's a free and easy way to get rid of it. It will take a few days to burn all the way down, and your BO will likely need to get permission from the local fire dept (unless you're rural).
We do this on occassion when too much manure builds up around our horses' shelter. We push the manure together and use pieces of cardboard folded up into long tubes stuck in random places to keep the fire going. It really just smolders for 2-3 days, then dies out. The leftover ashes are easy to spread or pick up. The volume is reduced by about 80%.
